Title: Hydraulic motor
IPC: F03C1/06
Filed: 1975-03-14
Abstract: 1501695 Hydraulic reciprocating motors DBA 14 March 1975 [27 March 1974] 10674/75 Heading F1A A reciprocating piston hydraulic motor is disposed in a pressurized enclosure (not shown) and the cylinders (11 1 ), 11 2 , (11 3 ), 11 4  are connected in turn through pipes 12 to the enclosure and to exhaust, whereby the pistons 2 move to cause step by step movement of an output shaft 7. Each pipe 12 is connected to exhaust of enclosure pressure via a selector switch (not shown). At the end of each piston's inward stroke, the piston engages a respective limited stroke buffer piston 13, the  flanged outer end surface 15 of the latter being subjected to the pressure within the enclosure. The pistons 2 drive the shaft 7 via links 9 and a plate 6 rotatably mounted on an inclined portion of the shaft 7. A rotary distributer valve 17 having arcuate grooves 18, 19 in its periphery is driven by the shaft 7, the grooves being connected, respectively, to the enclosure pressure through a groove 20 and to exhaust through an annular groove 21. As the valve 17 rotates two openings (not shown) linked to a numerical pressure detector communicate with the grooves 18, 19, the resulting changes in pressure enabling the detector to indicate the displacement and direction of rotation.

Abstract: 540,591. Moulding accumulator casings. VARLEY DRY ACCUMULATORS, Ltd., and SZPER, J. A. June 22, 1940, No. 10767. [Class 87 (ii)] [Also in Group XXXVI] In a dry accumulator, the casing is moulded around the electrodes and porous separators. The electrodes 10, 11 may be separated by glass wool in sheet form 12 treated with rubber latex and a filling material such as diatomaceous earth, aluminium oxide, or aluminium silicate. The separators may project slightly as at 13, Fig. 3, the projecting parts being then bent around the edges of the electrodes to produce a continuous layer 14, Fig. 4, of separating material. A further sheet of separating material may be placed around the electrode assembly, around which the outer casing 22 is formed by a moulding process which forces the casing material into intimate contact with the whole outer surface of the electrode assembly. Before the moulding operation, a porous pottery or ebonite block 48 to support the vent tube 30 is arranged as shown with its ends beneath the connection bridges 16, 17 and filling material 21 added so that the electrodes, separators, bridges and block form a compact and solid block. The vent tube 30 rests on the top of the porous block 48 and may be formed integrally with a porous partition which closes the inner end of the tube to prevent the escape of solid particles. The casing may be composed of hard rubber or ebonite or synthetic resin. The casing may be roughly formed, the electrode assembly inserted and the whole placed in a separable mould, heat and pressure being applied so that the casing material flows and forms a continuous and homogeneous casing in intimate contact with the electrode assembly ; or the assembly may be inserted in a mould, the casing material being added in the form of sheets or as a liquid or powder. The initial part of the curing process may be carried out in the mould under heat and pressure and the battery then removed from the mould and transferred to an oven where the curing is completed. Various alternative methods of forming the casing are briefly described involving spraying, dipping, cold-casting &c. In one of these a latex mixture is poured into a porous plaster mould in which the electrode assembly is positioned, the rubber depositing on the electrodes due to absorption of moisture by the porous mould.

Title: Improvements relating to electric energy meters
IPC: G01R11/36
Filed: 1949-04-23
Abstract: 691,299. Supply meters. LOPEZ, C. R. April 23, 1949 [July 13, 1948; Aug. 2, 1948], Nos. 10835/49 and 10836/49. Class 37. A standard type of single phase assembly is associated with an inductive device to form a fraud-proof meter. The inductive device consists of current and voltage coils arranged to produce a rotating field to rotate the meter disc and prevent incorrect registration which would otherwise occur with immobilization of or interference with the standard assembly. In Figs. 10 and 11 the standard assembly is shown on the left and the inductive device on the right. If in Fig. 10 there is unbalance between the phase and neutral currents the fluxes produced by series-opposing coils 2A, 3A do not counterbalance and a net alternating flux in voltage magnet 1A induces a voltage in a secondary coil 9A and this voltage drives a current through a current coil 10A on current magnet 12A so that a rotating field is created by 1A, 12A to drive the meter disc. To ensure 90 degrees phase difference between the driving field in voltage magnet 1A and the driving field in current magnet 12A the coil connecting lines 6A are given a predetermined resistance. If an attempt is made to perpetrate a so-called " crab fraud " creating 180 degrees phase difference between the driving fluxes in the standard assembly, the inductive device prevents reverse rotation of the meter disc since the coils 2A, 3A under this condition are effectively in series-aiding and the disc rotates at the correct speed. In Fig. 11 the current magnet 12A is provided with two counterbalancing windings 10A, 13A, as in the voltage magnet 1A, which in this case does not have an output or secondary winding and the effect is similar to Fig. 10. The Specification includes full constructional details, Figs. 1 to 9, and 12 to 14 (not shown). All the coils may be located beneath the meter disc.

Title: Method and apparatus for feeding liquid fuel to internal combustion engines
IPC: F01L5/06
Filed: 1930-04-07
Abstract: 358,945. Supplying liquid fuel. FRENCH, L. O., 708, North Plankinton Avenue, Milwaukee, Wisconsin, U.S.A. April 7, 1930, No. 10968. Convention date, April 15, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 7 (iii) and 7 (vi).] Liquid fuel is delivered to the combustion chamber in the form of a thin film carried by a rotating or oscillating disc 19, the fuel being vaporized by a current of air directed over the exposed area of the disc by the form of the combustion chamber and piston head. The fuel is supplied under gravity or light pressure from a supply tank 29 to a passage 22, Fig. 3, leading to a concealed portion of the disc 19. The disc is held in contact with the face of a detachable and jacketed plug 21 by a spring 38. A charge of air, drawn into the crank chamber through a port 14, is compressed and transferred through a port 16 ; an exhaust port 15 is located diametrically opposite the transfer port. At the end of the compression stroke the air charge is forced at high velocity into a pocket 26 containing an ignition device 56 at its further end, the air stream vaporizing the film of fuel as it is exposed by the disc. An oscillatory movement of the disc is effected by a bevel segment 40 which meshes with a bevel wheel 39 secured to the stem 20 of the disc, the segment being actuated by a rod 45 reciprocated by suitable cam mechanism. The rod 45 is hinged to allow the top to be moved in an arcuate slot 43 to vary, according to load, the travel of the segment and thence the area of fuel film exposed per cycle. Alternatively, the stem 20 may be given an intermittent rotary movement by a skew gear, the driving shaft of which is rotated unidirectionally through a ratchet or clutch by the movements of the rod 45. An air pump 30 maintains a light pressure in the tank 29.
